James G. Brown 2 of 3 |

SPECIFICATION forming part of Design No. 33,562, dated November 13, 1900. Application filed October 19, 1900. Serial No. 33,661. Term of patent 14 years. | ||

To all whom it may concern: Be it known that I, JAMES G.
BROWN, a citizen of the United States, residing at
Cleveland, in the county of Cuyahoga and State of Ohio, have invented
and produced a new and original Design for Prism-Plates, of which
the following is a specification, reference being had to the
accompanying drawings, forming a part thereof.
Figure I is a view in perspective of a
prism-plate embodying my design. Figs. II and III are views of opposite
side edges of the plate.
My said design for a prism-plate comprises
two series of ribs formed upon one and the same side of the plate. All
of the said ribs are parallel and extend transversely of the plate. The
ribs 6 of one of the series of ribs alternate with the ribs 7 of the
other series of ribs. All of the said ribs project the same distance
from the body portion 5 of the plate. Each rib 6 has two curved sides or
faces 8 and 8, that extend from end to end of the rib and curve outwardly
and converge from the body portion. Each rib 7 has two flat and straight
sides or faces 9 and 10, extending from end to end of the rib and
converging from the
|
body portion of the plate. The face 10 of each rib 7 is arranged at
greater angle to the plate's body portion than the other face 9 of the
said rib and is consequently not as wide as the said face 9.
The essential feature of my design consists
in the two series of parallel ribs formed upon one and the same side of
the plate, with the ribs of one series alternating with the ribs of the
other series, and with straight flat faces formed upon the ribs of one
of the series of ribs and with curved faces formed upon the ribs of the
other series of ribs.
A prism-plate having the design hereinbefore
described is remarkable for its brightness and is beautiful in appearance.
What I claim is—
The design for a prism-plate as herein shown and
described.Signed by me at Cleveland, Ohio, this 10th day of October, 1900.
